Abu Dhabi: Gulf Cooperation Council (GCC) countries on Saturday condemned what they said was Iranian interference in the internal affairs of Saudi Arabia and the region.
"The ministerial council strongly denounced these acts by Iran and stated that Iran carries the responsibility for these acts," it said in a statement after an extraordinary called to discuss tensions.
Meanwhile, Iran has said Saudi Arabia is to blame for the diplomatic crisis.
In a letter to the UN Secretary-General Ban Ki-moon published by Iranian news agencies earlier on Saturday, Iran's Foreign Minister Mohammad Javad Zarif complained about Saudi Arabia's "provocations" towards Tehran.
In the letter, Zarif said "some people" in Riyadh seemed bent on dragging the whole region into crisis.
Zarif said Iran had "no desire" to escalate tensions further, but offered no compromise.
Saudi Foreign Minister Adel Al Jubeir said on Saturday that Saudi Arabia may take further measures against Iran after cutting ties this week.
Jubeir's comments came in a press conference after an extraordinary meeting of the GCC foreign ministers.
"We are looking at additional measures to be taken if it (Iran) continues with its current policies," Jubeir said, without elaborating on what these measures could be.
"The escalation is coming from Iran, not from Saudi Arabia or the GCC .... We are evaluating Iran's moves and taking steps to counter them..things will be clearer in the near future," Jubeir said.
Jubeir also said his country had asked the Organisation of Islamic Cooperation, of which Iran is a member, to convene an extraordinary meeting to discuss the aggression against its embassy.
